Top: average Ca ii K line of φ Leo from 2015 December 20 and 23 (red continuous line), together with a Kurucz photospheric model (blue dash-dotted line). See text for stellar parameters. Middle: residuals of the average 20 and 23 spectra with respect to the photospheric line. The blue continuum line is a Gaussian with FWHM = 56 km s-1. Bottom: observed Ca ii K line (red line) of α Aql compared with a Kurucz model (blue dash-dotted line) with stellar parameters Teff = 7900 K, log g = 4.25, vsini = 210 km s-1.
